FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed February 5, 1914. Serial N o. 816,776.

T0 all whom 'it may concern.'

Be it known that I, VILLIAM F. ULLRICH, a citizen of the United States,residing at Warrenl inthe county of Warren and State of Pennsylvania,have invented certain new and useful Improvements in Fountain-Pens; andI do` declare the following to be a full, clear, and eXact descriptionof the invention, such as will enable others skilled in the art towhichjit appertains to make and use the same.

Myinvention relates' primarily to fountain pens but more especially tothat class of the latter which employs two pens in conjunction with asingle barrel.

A One object of my invention is to provide a duplex fountain pen of thischaracter, having two reservoirs adapted to contain dilferent coloredinks, and possessing facilities whereby each pen point 'can beseparately supplied, and used as conveniently as a pen having but asingle pen point.

Another object of the same is to construct a fountain pen having alsingle reservoir but provided with two pen points of different qualitieseither of which can be used when desired.

Another object of my invention is to provide a head adapted to bedetachably enga ged with the barrel and having means for forming anink-tight oint when it is in engaged position.

With these and other objects in View, my invention consists of certainnovel details of construction and combinatiom;` and arrangement of partswhich will be more particulai-ly pointed out and claimed.`

In the accompanying drawings in which similar' parts are designated by|corresponding numerals: Figure'l is a side elevation, partly in sectionof my improved fountain pen; Fig. '2 is a similar view of the pensupporting head, the sleeve being illustrated in a disconnectedposition; Fig. 3 is a transverse longitudinal section'illustrating myimproved pen in assembled condition; Fig. 4 is a transverse verticalsection taken on the line 4 4 of Fig. 3; Fig. 5 is a similar view takenon the line 5-5 of Fig. 3; and Fig. 6 is an end elevation of my improvedpen supporting head illustrating the yieldable hemispherical sectionsformed on the latter.

In its present embodiment my invention comprises a barrel 1,-slightlytapered at the one end and externally threaded as at 2. A

transversely disposed longitudinally extend# ing partition 3 formed inthe barrel 1, di vides the latter into two separate chambers 4 and 5which actas reservoirs for the dif'- ferent colored inks.

.'Ielescopically` engaged with the one endl of barrel 1, is'a penholding head 6, cylindrical in conformation and provided with twoadjacently disposed longitudinal channels 7 and in the latter aresuitably disposed two ink feeders 8. Pen points 9 are mounted back toback with their upper portion disposed with said channel in operativerelation with said'feeders. In this connection it will be noted that oneof the Walls of channels 7 are` convexedly' shaped so as tosubstantially conform to the shape of the pen. Extending around thehead6 nearthe inner end thereof is an annular shoulder 10 the purpose ofwhich will be" hereinafter explained.

To individually connect each pen with one of the reservoirs so as toavoid any possibility of the ink in one reservoir intermingling withthat of the other as it flows to thepen, or likelihood of the inkreaching the exterior of the pen to stain the fingers, I slightly taperthe inner end of the head 6 and form the latter With a transverse slotl1, which it will be seen divides said end into two hemispherical shapedextensions or sections 12 and 12, each containing one of the channels 7carrying the feeders 8 andpen points 9. By this construction andarrangement when the inner end of head 6 is telescoped into the barrel,one of said sections or extensions will project into each reservoir, andowing to the tapered formation of the inner end of the barrel l and thehead 6, the sections will be vthreaded end of barrel 1, forming a simpleconnection for retaining the head in proper position. Openings 15 areformed in the outer end of barrel 1 to permit the latter to be readilycleaned when necessary, said opening being closed by the threadedplugs-1G. A cap 17 is provided for the proi' tection of the penpoints'9.

rIhus it will be seen that I have provided a duplex pen, which issimple, easy to construct and one in which it is absolutely impossiblefor the two inks in the reservoirs to intermingle owing to illy-uniquemethod of connecting the head and barrel.

From the foregoing description taken in connection with the accompanyingdrawings, theV construction and operation of the invention will bereadily understood without requiring a more extended explanation.`

Various changes in the form, proportion and the minor details ofconstruction may be resorted to Without departing from the principle orsacricing any of the advantages of the claimed invention.

What I claim as new is A fountain pen comprising a barrel closed at oneend and having its inner surface con tiguous to its open end flaredoutwardly, a longitudinally extending partition disposed therein, saidpartition forming reservoirs, a slotted cylindrical head telescopinginto said barrel, said head having oppositely disposed longitudinallyextending channels therein, the inner end of said head being slightlytapered and transversely slotted to receive one end of said partitionand to form yieldable sections, each having an opening therein wherebywhen the inner end of said head'is telescopically engaged with theoutwardly flared end of the barrel/and,

be compressed so as to be brought into frictional engagement with theopposite faces of said partition, thereby forming an ink-tight joint,feeders disposed in said longitudinally extending channels, pen pointsdisposed in the latter in operative relation with said feeders, and avsleeve threaded on said barrel and inclosing said head, there beingengaging shoulders in said sleeve and on said head, whereby the latteris securely-fastened to said barrel.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
